For a dozen or so years, we have been witnessing an on-going, global discussion, concerning the shape and dimension of the cadastral system. Legal and technical standards are created, regulating the rules of its management, defining both the system itself, and the objects registered in it. From the point of view of building the cadastre in Poland, the most important of these standards include the INSPIRE Directive and the Polish Norm PN EN ISO 19152: 2013-05E. The present research aims to analyse the compliance of national regulations with international requirements, and to verify their applicability in practice. As our research material, we have used the source texts of the most important legal regulations and norms in the field of real estate cadastre, and we have analysed those in terms of legal and technical possibilities for the construction of a 3D cadastre in Poland. In addition, our study is anchored in descriptive data from cadastral databases of the EGiB units located in the Podkarpacie region. Our research concerned the determination of the scale of discrepancy between the data recorded in the land and building registry system (EGiB), and the data from the land and mortgage register (KW). The results of the analyses we have carried out consist in indicating the main obstacles to the construction of a multi-dimensional cadastre in the Polish reality. The last stage of the research work was an analysis of the compliance of spatial data, in terms of the consistency of objects registered in various databases of geodetic character. The graphical elements from surveying materials, originating from the Małopolska region, served as our research material. The absolute compatibility of object topology is a prerequisite for the functioning of the cadastral system. On the basis of the results obtained, the proposal of a multi-purpose system was discussed, that would employ the existing databases, with the possibility of transforming the dimension – from 2D to 3D. Based on a detailed analysis of legal and executive acts – in the field of real estate cadastre in Poland and in the world – as well as a survey of geodetic materials in terms of geometric and topological data compliance, it can be concluded that the cadastre in Poland requires further changes. The presented problem is valid and important in the context of introducing the third dimension of data to the real estate cadastre.
